The video out connections are a single S-Video out and an exclusive feature of MSI's video cards, The Mazarine DVI output. This connection allows for using a DVI to HDMI adapter to output both high definition audio and video through a single connection. This port also allows the display of an image on a digital display up to a resolution of 1920x1200. The button with the TT on it is the Twin Turbo button. This is where the one touch overclocking of the shader and core clocks are set. The real magic happens with the activation of the second BIOS chip when this button is pushed.
